Dont have that many bud. After Glen I'll only have 18 left but you are welcome to them..

Think “5S” when setting up shop.

Stuff you use most should be closest; least, furthest.

Beginning with that 400 S2 is a fantastic idea. You'll learn a lot, plus have a nice amp to listen to once finished.
Those D500s have a lot more going on inside them than a 400 or 700.

From the way you build a motor bud, lookin forward to what you can do with some electronics...

Ok, digging around I found another box of green. Got 170 green and 84 black.
So it looks like there's enough to do all 4 500's and the 400 .
Piles of 10..

Same way in the oilfield Davis. You can take one look inside a water plant or main battery and tell if a hack did the work..we redo all water plants we acquire through well purchased in stainless piping and stainless or aluminum bronze valving. Aluminum bronze is almost as corrosion resistant as stainless. A LOT of triplex fuid ends are AB, easy to machine and just plain tough..

Boards are built. Now for the ugly job of cleaning them. I don’t like acetone so I get my gloves and respirator on for this.

 

[George S.]

Glenn, do you leave R41 L+R out when you build these for a D500?

 

[grapplesaw]

Grapplesaw,

I *think* something caught my eye with this diode? Is this diode installed correctly, and this is a silkscreen error?

Or did I somehow saw this incorrectly interpret this on my end?

If not, then it looks like the diode is reversed on your board?

Please give it a look...

Well done. Sure enough got one of 8 wrong. I always look the boards over from head to toe before powering on but this is a great save.

No I put them in

I stole them for a project and have them on order. Should be here tomorrow
